How to evict an inherited tenant?

[John Lamb]

I purchased a property from a wholeseller that has a tenant in place. The contract said there is a 10 day post-possession to allow the tenant time to move. After talking with the tenant they are making every excuse for not being close to moving (junk in the house/yard, 7 cats, can't find a place). They only have a few more days to be out of the property, so I'm concerned that they won't be out on the agreed upon date. Because this is an inherited tenant, and I won't be renting to them, I don't have a lease agreement in place. The contract I signed was between the seller and myself, so how can I enforce the post-possession date for when the tenants have to be out?
